Nokia's (NYSE: NOK) Lumia 900 4G appears to be an initial hit, according to one source.

Taking a quick peer at Amazon.com's (Nasdaq: AMZN) best-selling mobile phone (with contract) list, Nokia's latest Lumia iteration is the clear winner. Both the black and cyan devices took the number one and two spots, with 5-star ratings on each (about 21 votes for the cyan and 62 for the black version).

Coming in third was Motorola Mobility's (NYSE: MMI) DROID RAZR MAXX, fourth was Samsung's Galaxy S II Epic Touch (which, we feel needs a few more words in its name), and Samsung's Galaxy Nexus 4G was fifth.

Of note, the first Research In Motion (Nasdaq: RIMM) BlackBerry device was 12th, with 27 raters giving the device an average rating of 2.5 stars, the lowest in the top 20.

Looking at AT&T's (NYSE: T) wireless site didn't reveal any more clues about the Lumia 900, only that it received a near-5-star rating from 20 customers.
